The brake shoe 165' which; is .con-

During the single revolution of the cam shaft,

the cams I83 engage-the camrolls 182 to move the links 178 downward and thus rotate the shaft 5andcrank .arms' 44 in a clockwise direction I .as viewedin Fig. l to move the presser foot into engagement with the upholstery along a line spaced from the edge. of the latter and to compressand produce a cavity therein, asshown inFigs. 5- to,8 inclusive. Thecams '191 then actuate the levers 188 to rotate the collars 97 upon the shaft and move the member 95 from the positionshown in Fig. 4 to that shown in Fig. 5. At the same time the intermeshing gears 193 and 194 rotate the shaft 195 and inasmuch as the shaft 195 is operatively connected with the shafts 62 through thecrank arms 196 and 197 and thelinks 198, the shafts 62 andshaft 63 are caused to rotate. Inasmuch as the shafts 63 and 76 are operatively connected by the gears 10 and 199, these shafts. are oscillated in opposite directions.

Thus, the arms 65 carried by the .shaft 63 are moved in the direction of the arrow inFig. 5, causing thefingers '72 to pierce one of the upholstery fabrics and to engage a part of the stufiing between the fabrics and. push the same beyond the edge of the upholstery,. as viewed in Fig. 6. At the same time the knife -83 carried bythe shaft 76 is moved in thedirectionof, the arrowin Fig. 5. The arms 65 and V knife 83 are then caused to movein the opposite directionas indicated by, the arrows in Fig.6 .and at thesame time the'member 95 moves, to- :wards its initial position inthe direction indi'-.

cated by the arrow in Fig. '7, until theseparts reachthe positions shown inFig. 8, whereupon the knife 83 cooperates with the blade to sever the portion ofthe stufiing pushed beyond the edge of the cushion. The member moves slightly in advance of the knife 83 and the teeth 98 thereon move into the spaces betweenthe arms 65 and serve to strip the removed stuffing while the knife seversthe same. This operation of the arms 65,'knife.83, and member 95 is again repeated inasmuchas the ratio of the gears- 193 and 194is ,two to one. By this time the cam rollers 182 carried at the lower ends of the links 178 have reached the depressions in the cams 183 thereby permitting the springs 33 to raise :the presser foot [30 out of engagement with the upholstery cushion. At thisrtimethe cam shaft 127 has just completed its single revolution and the inclined surface 159 on the bolt 152 engages the cam surface 158 on the slide 134 to cause the bolt to be released from the radial I slot 160 and thus disconnect the source of power from the cam shaft. 7
